additionaly to what @raven-worx said, you can try setting this windowflag setWindowFlag(Qt::MaximizeUsingFullscreenGeometryHint,true); this should paint the window over everything.

Upgrading to 5.6 solved my issue.

@SGaist Thanks Champ, I am checking it.

Thanks for the google map plugin, I study this post, the codes of your plugin and got some questions 1 : All of the information of google map are obtained by static api of google map? 2 : How could we support offline routing, offline search by term? By now all of the routing information are get from the server, to implement offline routing, we need to a : download require map, data from the server b : write our own algorithms to search the locations by terms and routing? I guess every maps data got their own format, but the locations searching and routing algorithms should be the same? 3 : QGeoTileFetcherGooglemaps is the main class of this plugin, which in charge of create request(by static api) and get the results back by the other classes? Thanks a lot

@mrjj Oh thank you very much. It's a good thing to learn!

Hi and welcome While using QStackedWidget for all pages / screens could work just fine, a more common design would/could be using QDialog for welcome and login and when closed - the main window for the graphs etc.

@VRonin Thanks!, this is what I ended up doing in the end, I just wondered if there was a nicer way like StackView.

This looks very promising, thanks ! :)

@p3c0 it does yet I wanted to fix the problem I personally faced thanks for an advice
